-' joining the holes I described, the button is simp -Be it known that I, CHARLES E. ONGLEY, a citizen of the United States, and a resident of the borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvements in Button-Sewing Attachments for Sewing-Machines, of which the following is a specification.

Thisinvention relates to a button sewing attachment for sewing machines.

The organization of the invention primarily comprlses means, by which either a two hole or four hole button can be sewed to a material, and in the latter case to be able to either sew the stitches diagonally across the button, 'or on the perimeter line joining the button holes of the button. The stitches diagonally across the button will overlap each other, and the stitches on the perimeter line will be consecutively adjacent to each other. These new technical effects are produced by moving the buttons in the requisite paths under the point of a needle of a sewing machine, and in the case of a two hole button it is reciprocated in a practically straight stitches are to follow the rections parallel to such perimeter, stitches are formed.

Referring to the drawin s; Figure 1 represents a front elevation of t e invention, wit a fragmentary view of a sewing machine to which it is attached, Fig. 2 shows a plan view of the invention, Fig. 3 is a partial section of Fig. 2 on the line 3, 3, Fig. 4 represents a fragmentary portion of Fig. 1 with some of the ositions, Fig. 5,is a left parts in changed and end view of ig. 1, Fi 6 shows a right I hand end view of Flg. 1, Fig. 7 represents a of one of the clamping jaws, Fig. 8 shows a plan view of a portion of the clamping device, Fig. 9 shows a two hole button with its stitches, Fig. 10 shows a four bottom plan view hole button with the stitches diagonally across the holes of the same, and Fig. 11 represents a four holebuttonwith stitches passing through the successive holes in the button forming a polygon.

The frame 20 of the attachment is fastened to the bed plate 21 of a sewing machine, with screws 22. From the frame 20 extends the journal bracket 23, which'supports the journal pin 24, for the bell crank 25 with the arms 26 and 27. The arm 26 has a forked end 28 which straddles a screw 29, that extends from a collar 30, supported on the needle bar 31 of the sewing machine. To the needle bar is secured the needle 32 in the ordinary manner.

A spur gear 33 is journaled on a journal pin 34, that extends from the frame 20. It

as the gear teeth 35 extending from its circumferential edge, and the ratchet teeth 36 projecting from its upper face.

A in 37 extends from thearm 27 of the bell crank 25, and on the latter is journaled a pawl 38 with the hook end 39, which latter can engage with the ratchet teeth 36. A spring'40 extends between the arm 27 and journaled end of the pawl 38. The pawl has a pin 41 extending from its side.

From the frame 20 extends the journal bracket 42 which supports the journal pin 43 for the'ratchet interrupter arm 44, that has the lug 45 extending from its free end, and the said lug is located to normally ride on the upper face of the smooth portion of the spur gear 33. Ratchet interrupter pins 46 are screwed into the upper face of the wheel 33, located so as to engage with the lug 45 when operating the said attachment.

A lug 47 extends up from the frame20, into which is secured a journal pin 48 for the link 49, which latter carries the journal pin 50, for the L shaped operating arm 51.

A journal pin 52 is fastened to and extends up from the frame 20. A sleeve 53 is supported on the pin 52, and is kept from vertical displacement by means of the screw 54, which can bear on a shoulder formed in said sleeve. At the lower end of the sleeve 53 are formed teeth constituting a pinion 55, which meshes with the teeth 35 of the spur gear 33. The u per end of the sleeve 53 terminates in a gui e 56 for the nut 57. Screwed into said nut is the journal pin 58, which latter can secure the said nutat different positions in the said guide, so that the distance between the vertical axis of the pin 52 and the axis of the pin 58 can be varied. A collar 59 of the operating arm 51 is journaled on the journal pin 58. To the end 60 of the operating arm is secured the guide block 61 by means of the screws 68. A cross head 62 is .adjustably clamped in different positions in the dovetailed guide 63 of the guide block 61, the cross head being suitably formed to fit the said guide. A screw 64 fits a threaded hole in the cross-head 62, and has shoulders 65 and 66 that bear against the upper and lower faces of the end 60 of the said L shaped operating arm 51. A slot 67 is formed in the said operating arm to allow the insertion of the screw 64. A milled head on the top end of the screw 64 allows the operator to turn the same, and thereby raise and lower the cross head 62 with its appurtenances.

From the cross head 62 is journaled the supporting arm 69 on the pin 70.

A pillow block 71 extends fromthe supporting arm 69 which supports a screw, with the right handed threads 72, and the left handed threads 73, the right hand end of the screw being supported in the journaled end of the supporting arm 69. Clampin jaws 74 bear on the supporting arm 69 an have threaded bosses 75 toengage with the threads of the said screw. Each of the clampin jaws has formed therewith the corrugated clamping surface7 6 which extends upwardly, from the lower face of the jaw for a portion of its thickness. The clam ing surface is angular in contour so that eac can clamp a button at two points of its circumference. A milled head 77. allows theturning of the screw, and

to be sewed.

collars 78 on the screw bear against the pillow block 71 maintaining the screw in place. A ca 79 is secured to the pillow block 71, and .it hasa hook 80 which is engaged by a hook 81, secured to the sewing machine. A s ring 83 extends from the cross head 62 and bears on the cap 79.

Below the supporting arm 69 is located the su orting plate 84, which is attached to gui e block 61 with the screws 85. The plate 84 has the opening 98 "to allow the needle to pass therethrough and coact with the other elements of the sewing machine. The su porting plate 84, and supporting arm 69 wit its clamping jaws and other appure tenances constitutes a clamping device, for the buttons and material on which they are A post 86 extends from the frame 20, and 1t carries the adjustable ratchet interrupter plate 87 having a longitudinal opening. A screw 88 in the post 86 allows the plate to be clamped in the path of the hook end 39 of the pawl -38.

In the lug 47 that extends from the frame 20 there'is pinned an adjusting bar 90 with the bent over 'ournal end 91. The bar is held from disp acement by the link 49 and pressure bar 82 of the its free end bears against the guide 56, to maintain it in-proper posltion after having been intermittently rotated. A spring 92 74, the latter being adjusted to the requisite distance apart, so that the buttons will be gripped by the corrugated surfaces of said aws, and made to bear on the said material. By this disposition of the buttons and material, slippage between the'buttons and material is avoided, when the attachment is in operation.

The diameter of the inion 55 being onefourth of the diameter oi the spur gear 33 the former Will make four revolutions when the spur gear is making one revolution.

When the sewing machine is operating for each up stroke gear 33 will be moved through an angle equivalent to an eighth of a revolution, equal to thedisplacement corres onding to two of the ratchet teeth 36 exten ing-from the spur ear.

g To sew a two hole button both interrupters are moved out of gear, that is to say the ratchet interrupter late 87 is moved to the right as shown in t e drawings, so that the hook end 39 of the pawl cannot ride thereon, and the ratchet interrupter pins 46 are removed from the spur gear 33, so that they will not actuate the swinging ratchet interrupter arm 44. At'9l button with stitches 92.

material, it is first determined whether the is shown a two hole of the needle bar 31,'the spur stitches for the four holes shall be at right angles to each other, as shown at 93 in button 94, or whether they shall follow one hole after another consecutively, as shown at 95 in button 96. I

To sew the stitches at right an les to each other the interrupter plate 87 is kept out of gear as shown 1nthe drawings, and the ratchet interrupter pins 46 are fastened to the spur gear, the number of them depending upon the nature of the stitches to be sewed. If oneof the pins 46 is located on the spur gear, then for one revolution of the said gear the needle bar makes eight double strokes or eight'stitches for two of the holes of the button that are diametrically opposite each other, for the next revolution the interrupter pin has actuated the ratchet interrupter arm 44 and the pawl during the action of said interrupter arm, instead of overlapping two teeth of the ratchet only a'ctu ates one, and the pinion with its guide and appurtenances is turned 90 degrees or onequarter of a revolution, and as for each re ciprocation of the pawl 38 I the pinion is .stitches in one direction, and then two at 3. In a moved a half a revolution, the effect will be spur gear, a bell crank pivoted on the atto move the clamping jaws now in a directachment, a pawl pivoted from an arm of the tion at right angles to the direction thereof, bell crank, a ratchet interrupter arm pivoted before the interrupting pin causes the pinion on the attachment, a pin extending from the to turn 90 degrees, then during the next awl and locatedto engage with the ratchet 7O revolution of the large spur gear, the stitches interrupter arm, a lug extending from the formed will be at right angles to the stitches latter arm bearing on the upper face of the formed in the previous revolution of the spur gear, means on the spur gear to engage spur gear, and thus during each revolution said lug and thereby raise the interrupter of the large spur gear, the directions of the arm and .pawl, a supporting plate, connecstitches will be changed. tions between sa'd plate and the operating When two ratchet interrupter pins are searm, a bearing arm pinned over the-supportcured to the spur gear 33, it is evident that ing plate, means to vary the distance befour stitches will be sewed in one direction, tween the supporting plate and. bearing arm, and four at right angles thereto for each revoclamping jaws bearing on the bearing arm, a 30 lution of the spur gear, pillow block on the sup orting arm, and a When four interrupter pins are secured to spring bearing on the pi low block to mainthe spur gear, then there will be sewed two tain the supporting arm in proper position.
